This manual is intended to replace the various (expensive) references needed to
|
|
program for the DOS environment, that stack of magazines threatening to take
|
|
over your work area, and those odd tables and charts you can never find when you
|
|
need them.
|
|
|
|
The various Microsoft and IBM publications and references don't always have the
|
|
same information. This has caused some consternation about the "undocumented"
|
|
features to be found in DOS. In general use, if a call doesn't appear in the IBM
|
|
DOS Technical Reference it is considered "undocumented" although it may be in
|
|
common use.
|
|
|
|
Microsoft's offical policy toward DOS has been to put the burden of documenting
|
|
and supporting their product to their vendors. Microsoft will not answer any
|
|
questions concerning DOS directly since they don't officially support it. This
|
|
leaves what information IBM and other OEMs (DEC, Zenith, et al) have chosen to
|
|
publish, and the information obtained from programmers who've poked around
|
|
inside it.
|
|
|
|
Now that Microsoft is selling MSDOS 3.2 and 3.3 as Microsoft products they seem
|
|
to be dragging their feet over whether they will have to support the generic
|
|
version since it doesn't have an OEM name on it anymore. In view of their push
|
|
to OS/2 (OS/2! Just Say No!) further support of DOS seems unlikely.
|
|
|
|
The information here is valid for DOS 2.x and 3.x. Where there are differences
|
|
between the two versions there are notes in the text. No effort was expended
|
|
on DOS 1.x or networking features.
|
|
|
|
As I write this there is still considerable furor over incompatibilities with
|
|
DOS 4.0. Since a Technical Reference for 4.0 isn't availible yet, I don't have
|
|
a whole lot of info on it.
|
|
|
|
When I started writing this book, it was originally for my own personal use.
|
|
Then I began expanding it with the idea of getting it published, since at that
|
|
time there was *nothing* in print like it. If I had managed to send it off to
|
|
the publishers early enough, I would have had it made. As it was I lost six
|
|
months having a nice steel rod put in my leg, and half a dozen similar books
|
|
were published by then, and nobody was interested in mine. Six months is a
|
|
long time in the PC world.
|
|
|
|
That's why I'm uploading this file as "user-supported." It gives me a chance
|
|
to recoup a few bucks for the year or so I've been working on this thing, and
|
|
it gives some advantages that a printed book can't - first, you can load it on
|
|
your hard disk and use Vern Buerg's LIST or SideKick to scan through text. You
|
|
can grab a peice of something and paste it into a document, etc. If you help
|
|
support the PC Programmer's Reference you will always have the latest version
|
|
availible; you can't "upgrade" printed books.
|
|
|
|
A project this size takes a LOT of time and effort. I've tried to verify all
|
|
the information I've received, but there's just too much for absolute certainty.
|
|
If you find any typos, incorrect information, or want to see something else,
|
|
let me know. If you have any more detailed information on something, PLEASE let
|
|
me know!

|
|
The information presented here was gathered from megabytes of files found on
|
|
BBS systems, conversations on a dozen different BBS systems, correspondence,
|
|
and every reference book I could get my hands on. On occaision, a number of
|
|
prestigious references didn't agree with each other. Where this has happened, I
|
|
have used the latest references. There is too much information here for me to
|
|
verify every fact personally. I have used my own judgement as to the
|
|
reliability of the sources.
|
|
|
|
This entire project was originally begun as a reference for myself, where I
|
|
put all the little bits of information I culled from various sources into a
|
|
whole and (hopefully) organized format so I could find them again when
|
|
nescessary. If you find anything that is incorrect, I would greatly appreciate
|
|
a card or letter telling me.
|
|
|
|
As is common these days, I have to make a "Notice of Disclaimer". I take no
|
|
responsibility for anything, and if anything you do with this book ruins you
|
|
for life or makes your dog bite you, or anything else, that's just tough.
|
|
|
|
I hope you find much use for this reference. It was a trip to write, too.
